Thread: can't rearrange simple equation!

Hi. I feel a complete simpleton. How do I get this:

(2 - x)²(3 - x) - (3 - x)

to be this:

(1 - x)(3 - x)²

I am utterly stuck with this. Thanks for any help!

take common and try solving, by expanding

thanx amul28. i don't know what i was doing wrong...

(3 - x)[(2 - x)(2 - x) - 1] = (3 - x)(3 - 4x + x^2)
= (3 - x)(3 - x)(1 - x)

cheers
